This static method can be used to pre-load entries into the internal cache.

When loading a list of cached-entries differing in only a single param, this method could be way faster: Preload all elements without taking the param being different into account to load the list within a single query. Later on the regular getCachedEntry() can be used to access entries available in the cache; the loading from the internal cache or the database is done by the class internally and transparent to the using objects.
